Vulnerability identifier: #VU18563

CSH Severity: Low

CVSS v4: 5.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]

CVE-ID: CVE-2019-11698

CWE-ID: CWE-451

Exploitation vector: Remote access

Exploit availability: No public exploit available

The vulnerability allows a remote attacker to perform spoofing attack.

The vulnerability exists due to incorrect processing of drag and drop operations. A remote attacker can create a specially crafted hyperlink that when dragged and dropped to the bookmark bar or sidebar and the resulting bookmark is subsequently dragged and dropped into the web content area, an arbitrary query of a user's browser history can be run and transmitted to the content page via drop event data.

Successful exploitation of the vulnerability may allow an attacker to steal user's browser history.
